Its name comes from the Mapudungun word 'chadi' meaning salt, because its fossils were found near a big salt flat.1 2

Chadititan lived about 78 million years ago in a dry area with sand dunes and palm trees around a small pond.2

Scientists found the first fossil record of tropical land snails together with Chadititan, showing the area was once wetter.2

No bony plates (osteoderms) were found with Chadititan, unlike some other titanosaurs.1

Chadititan belongs to a group called Rinconsauria, which are known for their slender bodies.1 2
